Add credential-aware submodule operations and a command to checkout a specific
tag or commit in a submodule without staging the parent repository.
- Backend (src-tauri):
- Export checkout_submodule_revision and implement checkout_revision which
validates tag vs commit inputs, verifies refs locally, and checks out the
submodule in detached mode without modifying the parent's index.
- Add optional username/password parameters to add_submodule and submodule_action
flows. Implement submodule_git to call run_git_authenticated when credentials
are supplied and classify auth failures by prefixing errors with "AUTH_FAILED:".
- Wire authenticated variants (operate_authenticated, add_authenticated) and
update fetch/update actions to use credentials where needed.
- Add unit tests covering authenticated submodule commands, auth failure
classification, and checkout-by-tag/commit behavior.
- Frontend:
- App.svelte: introduce credential prompt flow (withSubmoduleCredentials,
submit/cancel handlers), surface credential dialog on auth failures, and
wire credentialed calls for initialize/add/update/fetch operations. Hook up
checkoutSubmoduleRevision and listTags to the submodule dialog.
- SubmoduleDialog.svelte: add UI for selecting destination folder, loading
tags and checking out revisions; expose fetch action.
- CredentialDialog.svelte: include "submodule" action and adjust labels.
- Docs:
- README: document "Change commit or tag" and "Fetch tags & commits" behaviors.
The commit focuses only on enabling credentialed submodule interactions and
safe local checkouts of tags/commits; no other git behavior changes are made.
